WEFT-CASE FOR AUTOMATIC WEFT -REPLENISHING LOOMS.

Patented Jan. '7, 1908.

Application filed April 9, 1906. Serial No. 310.796.

T 0 all whom it may concern.

Be it known that I, HEINRICH OTTO BRANDT, British subject, and residentin Manchester, county of Lancaster, England, have invented certain newand useful Improvements in VVeft-Cases for Automatic Weft-ReplenishingLooms, 01 which the following is a specification.

This invention relates to the cylindrical weft case employed to carrythe cop or pirn of yarn in automatic weft replenishing looms, and isdesigned to provide an improved construction of weft case which willbereadily and easily threaded and may be termed selfthreading.

The weft case is constructed of cylindrical or approximately cylindricalform with a spiral slot or slit extending from end to end open at oneend to receive the weft cop or pirn and with a central eye at the otherend through which the yarn is delivered.

The invention will be fully described with reference to the accompanyingdrawings.

Figure 1. perspective view of the weft case. Fig. 2. longitudinalsectional elevation of same. Fig. 3. end elevation. Fig. 4. endelevation with eye plate E removed. Fig. 5. perspective View showingmodified form of the thread slot and thread eye. Fig. 6. end elevationof same showing the thread slot g open. Fig. 7. end elevation of sameshowing the thread slot g closed.

The weft case A which is of cylindrical form and open at one end isconstructed with a spiral slot or slit at extending from end to end andforming a weft passage through which the thread from the cop or pirn iscar ried to a thread eye I) at the other end. This spiral form of slotor thread passage a renders the weft case A less liable to lose itscylindrical shape than where a straight slot or passage is employed.

The cop or pirn skewer or peg D is attached to a socket or cap D which[its over the open end of the weft case A and retains the adjacentparts, severed by the spiral slit a, in position.

The delivery end of the welt case A is closed by a plate or cover B witha central thread eye I) and a thread slot b leading thereto from thespiral slit (1. The plate or cover B is indented to receive a secondplate E, and into the indentation therein formed the eye plate E isfitted with a delivery eye 6.

The eye plate E is constructed with a slit in position upon the plate Bso that the eye .6 is coincident with the eye b but the slit 6" liesover the plate B and the slot 1) is covered by the plate E. E a recessor space 0 is left between it and the plate B through which the threadcan be drawn through the slot 1) under and around the edge of the plateE into the slit 0 and thence enter the double eye I) 0 formed by the twoplates. This construction prevents escape of the weft thread when thecase A is in the shuttle. The eye plate E is affixed by rivets brazingor other device.

In the modification shown in Figs. 5, 6, and 7 the case A is constructedwith a spiral thread slit or passage a, as before and with a plate G atthe delivery end in which is formed the eye 9 and slit 9 and upon theplate G is a projection g The second or eye plate H with eye It and slit71 is carried by a cap K with a slot is corresponding with the spiralslot or thread passage (1 in the case A and with an opening or recessIt" to fit over the projection g of the plate G. The eye plate H is caable of a limited movement over the plate in one position the slits gand it being coincident to lead the thread into the central eye gh (seeFig. 6.) and in the other position the slit 9 being covered by the plateH (see Fig. 7.) to retain the thread in position in the closed eye.

I am well aware that weft cases for automatic weft replenishing loomshave been formed with a straight slot or thread passage and such I donot claim.

What I claim as my invention anddesire to protect by Letters Patentis 1. A weft case constructed with a spiral slot from end to end to forma passage for the thread a delivery eye at one end and means forretaining the thread therein substantially as described.

2. A weft case constructed with a slot from end to end to form a passagefor the thread a delivery eye at one end a slit to introduce the threadfrom the slot to the eye and means for closing the eye to retain thethread therein substantially as described.

3. A weft case constructed with a spiral slot from end to end to form apassage for the thread a delivery eye at one end a slit to introduce thethread from the slot to the eye and means for closing the eye to retainthe thread therein substantially as described.

4. A weft case comprising in its construc- At one side of the eye plate.
